产品概述
The LM5070 power interface port and pulse width modulation (PWM) controller provides a
complete integrated solution for Powered Devices (PD) that connect into Power over Ethernet (PoE)
systems. The LM5070 integrates an 80V, 400mA line connection switch and associated control for a
fully IEEE 802.3af compliant interface with a full featured current mode pulse width modulator
dc-dc converter. All power sequencing requirements between the controller interface and switch mode
power supply (SMPS) are integrated into the IC. Two options are available providing either an 80%
maximum duty cycle limit with slope compensation (on the –80 suffix) device or a 50% maximum duty
cycle limit and no slope compensation on the (–50 suffix) device.
